Scorpion

Monday 10 September 2012

Scorpion:  Scorpions are predatory arthropod animals of the order Scorpiones within the class Arachnida. They have eight legs and are easily recognized by the pair of grasping claws and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm (Typhlochactas mitchelli) to 21 cm (Hadogenes troglodytes).Scorpions are found widely distributed over all continents, except Antarctica, in a variety of terrestrial habitats except the high latitude tundra. 

Scorpions number about 1,752 described species, with 13 extant families recognised to date. The taxonomy has undergone changes and is likely to change further, as a number of genetic studies are bringing forth new information. Scorpion venom has a fearsome reputation, and about 25 species are known to have venom capable of killing a human being. The word scorpion is thought to have originated in Middle English between 1175 and 1225 AD from Old French skorpiō, or from Italian scorpione, both derived from the Latin word scorpio, which in turn has its roots in the Greek word σκορπίος – skorpíos.
